The 2004 Chevrolet Silverado-1500 has overhead valves (OHV).
The 2004 Chevrolet Silverado-2500HD has overhead valves (OHV).
were is the cam shaft sensor
10mm
That year don't have one.
It is in the disturber itself.
sounds like the cam sensor or crank sensor or both are faulty, probably the cam sensor located on the distributor, under the cap
assuming you have a 5.0 or a 5.7 its its mounted on the distributor under the cap, it has 2 screws that hold it in
It is the only electronic device that you will find inside the distributor. Under the cap.
The timing is set on a 98 Chevy Silverado 1500 5.7L by aligning the cam sprocket with the timing chain markings. The engine's computer will then make adjustments on the fly for any additional timing changes needed.
Typical of worn bearings....crank, cam and rod bearings.
That requires a OBDII engine scanner. You can not use a timing light. The timing is computer controlled.
